The title complex, {[Cu(CH
4N
2S)
3]I·0.5CH
3CN}
n, was formed by the reaction of CuI and thiourea in acetonitrile. There are two independent Cu
I ions in the asymmetric unit which are coordinated by two terminal and two bridging thiourea ligands to form a one-dimensional helical chain structure progagating in the
a-axis direction. Each Cu
I ion is in a distorted tetrahedral coordination environment. The crystal structure is stabilized by weak N—H
S and N—H
I hydrogen bonds.

ABSTM02_ALERT_3_G When printed, the submitted absorption T values will be
replaced by the scaled T values. Since the ratio of scaled T's

does not imply a change to the absorption corrections used in

CuI (0.19 g 1 mmol) and thiourea (0.16 g 2 mmol) in 10 ml acetonitrile were
refluxed for 24 h, forming a colorless solution. After filtration, the
solution was allowed to evaporate slowly and crystals suitable for X-ray
diffraction were obtained after several days.
All H atoms were placed geometrically and treated as riding on their parent
atoms, with, N—H 0.86, C—H 0.96 Å, with Uiso(H) =
1.2Ueq(N), Uiso(H) = 1.5Ueq(C).

Special details top
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)
are estimated using the full covariance matrix. The cell e.s.d.'s are taken
into account individually in the estimation of e.s.d.'s in distances, angles
and torsion angles; correlations between e.s.d.'s in cell parameters are only
used when they are defined by crystal symmetry. An approximate (isotropic)
treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s.
planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor
wR and goodness of fit S are based on F2, conventional
R-factors R are based on F, with F set to zero for
negative F2. The threshold expression of F2 >
σ(F2) is used only for calculating R-factors(gt) etc.
and is not relevant to the choice of reflections for refinement.
R-factors based on F2 are statistically about twice as large
as those based on F, and R- factors based on ALL data will be
even larger. |

Some copper(I) compounds containing thiourea ligands have been described previously (Bombicz et al., 2004; Bott et al., 1998; Stocker et al., 1996). In this paper, we report the synthesis and the structure of a complex formed by the reaction of thiourea with cuprous iodide. The asymmetric unit of the title compound is shown in Fig. 1. The CuI ions have distorted tetrahedral coordination geometries formed by two bridging thiourea ligands and two terminal thiourea ligands. A one-dimensional helical chain structure parallel to the a axis direction is formed (Fig. 2). An iodide counter ion and half an acetonitrile solvent molecule complete the formula unit although there are two formula units in the asymmetric unit of the crystal structure. The Cu—S distances are in the range of 2.275 (2)–2.435 (2) Å, and agree with those in related structures (Bombicz et al., 2004). In the title compound, the S=C distances are the same within experimental error.
In the crystal structure, there are two different types of hydrogen bonds. Intramolecular N—H···S interactions appear to influence the conformation of the helical chains while intermolecular N—H···S and N—H···I interactions stabilize the crystal structure.
